使用 C# 从任何办公文件中剥离所有 VBA 代码

我想使用 c# 从任何办公文档中剥离所有 VBA 代码，我试图从代码项目中使用此代码：

string file = @"D:'AmlanSandbox'MacroRemoval'
    OfficeDocMacroUtility'OfficeDocMacroUtility'FileTank'Jhinku.docm";
object objTypeMissing = Type.Missing;
object filePath = file;
Microsoft.Office.Interop.Word.ApplicationClass wordAppl = 
    new Microsoft.Office.Interop.Word.ApplicationClass();
Microsoft.Office.Interop.Word.Document doc = null;
try
{
     doc = wordAppl.Documents.Open(ref filePath, ref objTypeMissing, 
        ref objTypeMissing, ref objTypeMissing, ref objTypeMissing, 
        ref objTypeMissing, ref objTypeMissing, ref objTypeMissing, 
        ref objTypeMissing, ref objTypeMissing, ref objTypeMissing, 
        ref objTypeMissing, ref objTypeMissing, ref objTypeMissing, 
        ref objTypeMissing, ref objTypeMissing);
     if (doc.HasVBProject)
     {
       wordAppl.OrganizerDelete(file, "NewMacros", 
    Microsoft.Office.Interop.Word.WdOrganizerObject.wdOrganizerObjectProjectItems);
     }
     doc.Close(ref objTypeMissing,ref objTypeMissing,ref objTypeMissing);
}
catch (Exception ex)
{
    throw ex;
}
finally
{
    wordAppl = null;
    doc = null;
}

但它没有完成这项工作。谁能帮忙？

doc.Save();
